HipChat service: correct service name & use v2 API

HipChat refers to their own product camel cased so we should do the
same. HipChat no longer recommends people use the deprecated v1 API so
switch to using the v2 API by default. hipchat-rb does not yet default
to v2 in any version so it must be specified.
